Rob and Kelly are having a "discussion" about the Psychic Phone Buddy Service:

Rob: "Kelly, guess what! I called my Psychic Phone Buddy and he told me it is going to be my lucky week! So, I went right down to the convenience store and bought two hundred lottery tickets. I'm going to win big!"
Kelly: "That's nice, Rob."
Rob: "What, you doubt that I'm going to win?"
Kelly: "Well, your chances are better than most people, since you did buy two hundred tickets. But, your chances are still about one in a million or worse."
Rob: "But, this is my lucky week. My psychic told me!"
Kelly: "Rob, that psychic stuff is a bunch of hogwash. Think about this. First, no one has ever been able to prove that people have such powers. Second, if you had psychic powers that let you predict the future, would you be working for some 1-900 company? I don't think so. If a person could predict the future, they would be out making a bundle on the stock market."
Rob: "Kelly, that is all well and good. However, no one has been able to prove that people do not have psychic powers."
Kelly: 'So you think that gives you good reason to trust your psychic buddy?"
Rob: "Yes, it does."

Rob watches the lottery drawing on TV that night and is horrified when he does not even win a single cent.Burden of ProofAppeal to the Consequences of a BeliefAppeal to BeliefConfusing Cause and EffectBurden of Proof: This is the right answer. Rob is accepting that his Psychic Buddy has psychic powers simply because no one has been able to prove that he lacks such powers. However, it is reasonable to expect people who claim to have special powers to be able to back up their claims with some sort of evidence. Thus, Rob is reasoning in a fallacious manner.Appeal to the Consequences of a Belief: This is a wrong answer. Rob is not asserting that his claim should be accepted because of the consequences of holding or not holding the belief.Appeal to Belief: This is a wrong answer, Rob is not accepting that his Psychic Buddy has psychic powers because most people believe that he does. In fact, there is no reference to what most people believe in this case.Confusing Cause and Effect: This is a wrong answer. Rob is not engaged in causal reasoning, so he cannot commit a causal fallacy.Rob believes that his Psychic Phone Buddy has psychic powers simply because no one has proven that he does not have such powers.1
